I came across a few miscellaneous mags in a box from an estate sale recently and have one that I can't positively identify. I've looked at hundreds of images and can't find one that matches it exactly, but the closest I've found is for a Beretta Bobcat 21 (.25 ACP). I'm hoping someone here will recognize it and can help me out. There is a large warning on one side that can be seen in the pics and I thought would help identify it but also no luck so far, but it says, "DANGER: This gun will shoot without the magazine in it. Use only factory loaded 50 grain full metal jacket ammunition." Any ideas?
